基于DAQ-2204的微弱信号数据采集与分析系统
Design of the Weak Signal Data Acquisition and Analysis System Based on the DAQ-2204
摘要
Abstract
In accordance with the requirements in the test of a certain magnetoelectric angle sensor, weak signal acquisition and analysis system based on DAQ-2204 data acquisition card is introduced. The system hardware is described. The data acquisition program based on LabVIEW is designed to capture weak floating signals. And the accuracy is improved through the correction to the signal acquisition driver. All experiments have showed that the system has a high accuracy and a wide application foreground in acquiring weak signals. And the system can be used to build fast, convenient, low-cost, multi-functional platform for weak signal detection.关键词
